Diagnosis
In the conntext of manual planning, you use the characteristicrelationships to generate all possible combinations. The systemdetermines a forecast for the total number of characteristiccombinations from the individual steps when generating thecombinations. This number is greater than the greatest number availableinternally for this (about 2bn.).

System Response
No combinations could be generated.

Procedure
Check the selection used for manual planning; This is not restrictedenough at all in the present case. You must possibly revise thedefinition of characteristic relationships, in order to reduce thepossible combinations.
